If you're fixing up a classic late-70s to mid-80s GM car, this brake caliper is made for you. Direct replacement for the rear left (driver side) on Buick Riviera (79-85), Cadillac Eldorado (79-85) & Seville (80-85), and Oldsmobile Toronado (79-85). Casting numbers 020L or 021R? This fits. Comes as a complete assembly—caliper, steel piston, and all the mounting hardware you need. Piston diameter is 53.87mm, ports are M10x1.5. It's coated to resist rust, so it lasts. Just bolt it on, bleed the brakes, and you're set. A-Premium backs it with a 1-year unlimited mileage warranty. Double-check your model and year before ordering, but if it matches, this caliper will get your classic stopping safely again without hunting for rare OEM parts.
